Vacuum brazing technology

Brazing is a technology for joining two metals using another metal (called the brazing filler material) with a lower melting point than the materials being joined. The materials are heated to the filler material's melting point, melting the filler material so that they are joined together.
MHI performs the brazing process under vacuum conditions in order to implement low-deformation brazing of parts that will be used under high vacuum conditions.

A high-energy particle accelerator built using state-of-the-art technologies
MHI products are highly regarded in a broad range of fields thanks to super-high-precision machining technologies and continuous/dissimilar material vacuum brazing technologies developed when the company manufactured the accelerating tube and ultra-high vacuum components for use in a high-energy particle accelerator.

An MHI-manufactured accelerating tube and acceleration cavity are being used in the High Energy Accelerator Research Organization's B-Factory accelerator, which was used in to demonstrate the CKM Ansatz proposed by professors Makoto Kobayashi and Toshihide Masukawa, both of whom shared the Nobel Prize in Physics in 2008. MHI products are also being used in the J-PARC accelerator that provides neutrinos to Super-Kamiokande, the experimental device used by Professor Masatoshi Koshiba, who won the Nobel Prize in Physics in 2002.
